Cross-dictionary
database triggers

When you respond to cross-dictionary database
triggers, you will typically need to retrieve values from the table
for which the trigger occurred. Because this table isn’t available
when you write your trigger processing procedure, it must be passed
into the procedure as an anonymous table. You can then use the
column() function to
retrieve specific field values from the table.

For example, the following script is the trigger
processing procedure for the delete trigger on the Applicants
table. Notice that the table is passed to the trigger processing
procedure as an anonymous table. Also notice that the
column() function is used to
retrieve the value of the Applicant Number field in the table.
